@suihkulokki ah good!

I recently bought an 8bitdo keyboard which comes with a pair of large “Mashable” programmable buttons. I mapped them to shift+ctrl+c and v, which works in my terminal and several apps which want ctrl+c and ignore the extra shift. They are surprisingly handy! Sadly Firefox didn’t.

What I found most 'interesting' in this article is that you don't need to reprogram your keyboard to send out a copy or paste key code. You can just use xmodmap or similar to reprogram your keys, no difference in your hardware required!
